I started my oil cooler project today and I'm using an Evo 9 OFH. Figured I'd post up some progress and information in case others are interested.
Note that this only works on 7-bolts.
Evo 9 OFH - 1230A018
Evo 8 OFH - MD372813
Either will work, the 9 OFH just has an additional 1/8" BSP port that the 8 OFH does not.
Bolts to use:
Upper holes - MF241261 - 8x1.25x40
Lower left - MF241266 - 8x1.25x65
Lower right - MF241268 - 8x1.25x75
These are all from the stock 2g OFH and happen to be the right length; you just need to buy another MF241261 since the 2g only uses one this size.
Gasket:
Evo - MD322522
2g - MD185528
Upper Evo
Lower 2g
You can see that the gaskets are identical for the most part, but the Evo has one hole the 2g doesn't, and vice versa. The extra hole in the Evo gasket doesn't even line up with a hole in the Evo OFH, so I'm not sure why it's there. The extra hole in the 2g gasket lines up with a recess in both the OFH and front case, but it doesn't seem the recess is used for any purpose. I'll probably use the 2g gasket though just to be safe.
And here are pictures of it installed. The bottom of the filter sits at about the same level of the oil pan, and above the downpipe and crossmember. Also, the bolt hole for the lower timing cover lines up perfectly
This is with a metric to -10 adapter and low profile -10 fitting. The fitting sits slightly lower than the filter. On the side port there is no way to fit this combination with the splash shield in place, so I'm most likely going to use banjo bolt fittings for both ports.
And with the splash shield on. There is about 3mm of clearance between the splash shield and OFH at the tightest point, but I was surprised how well it fit.
